- ART OF MAKING GAN-SEAMS.

Specification of Letters Patent. Patented Mar. 29, 1910.

Application filed December 19, 1906. Serial No. 348,532.

To all whom it may concern:

Be it known that I, CHARLES W. GRAHAM, residing at Rome, in the countyof Oneida and State of New York, have invented certain new and usefulImprovements in the Art of Making Can-Seams, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to the like.

One of the objects thereof is to provide a simple and practical artwhereby eflicient can seams .or other joints may be formed.

Another object is to provide an art of the can seams and above generaltype characterized by economical use of material, high speed of working,and independence of complicated machlnery.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists-in the several steps and the orderand relation of each of the same with respect to one or more of theothers thereof, all as will be exemplified in the matter hereinafter setforth and indicated in the following claims. In the accompanyingdrawings, wherein 1s indicated one of various possible embodiments ofthe product of my art and a manner of carrying on the same,Figure 1 is aplanview of apparatus whereby certain steps of my art may be carried on.Fig. 2 is a sectional elevation taken on the line-:z2ar; of Fig. 1. Fig.3 is a plan of a -notched blank. Fig; 4 is a side elevation showingcertain portions thereof flanged. Fig. 5 is an end view showingthe edgesinassembled relation. Fig. 6 is aside elevation of the completed joint.v Similar reference characters refer to simi lar parts throughout theseveral views of the drawings.

Considering first the illustrative method of carrying on my art shown inthe drawings and the apparatus therein set forth, there appears at 1 adriving pulley adapted to transmit power through the gears 2 and 3 to ashaft 4:, from which power is led through bevel gears 5 to the shaft 6.From the latter shaft, by means of the spiral gears 7 and inclinedshafts 8, gears 9 are driven, the latter parts intermeshing with gears10 and '11 respectively mounted upon shafts 12 and 13. Shaft 12 isprovided with rotating sition, the jaws being actuated through links 23from a spring depressed cross head 24 intermittently raised as by cam 25uponj m shaft 6.-

Mounted adjacent abutments 19 and 20 are rotary flanging devices 26driven from shaft 6 by the inclined shafts 27 and the spiral gearingindicated.

A sultable supporting table 28 is provided for the raw material, and ifdesired suitable guides may extend therefrom tothe table 15 and theclamping jaws above described.

Referring now to the manner of carrying on my art through the aid of theabove described apparatus, it being assumed that suitable rectangularblanks are placed upon table 28, as indicated by the dotted lines, theseblanks are transferred to the table 15 and the cutters 14 and 17 drivenas above indicated, respectively form in the adjacent edges of the blank\l -shaped notches 2 9 and rectangular notches 30, as best shown in Fig.3 of the drawings. From this point the blank is placed beneath abutmentsl9 and 20 and the clamping jaws 21 and 22 being thrownupwardly the sheetis securely held in position; with its outer edges projecting slightlybeyond the corresponding parts of 4 of the drawings, the edges arebrought.

into engagement one with another and the flanged portions hooked onewithin the other, or interlocked as-indicated in Fig. 5. Porby tions 33,however, rest smoothly against the inner surface of the opposite edge ofthe the jaws. .The-"blades-of flanging devices '13" 26 thereupon engagethe projecting edge 31 blank, and form therewith a lap joint as invdicated at 34:, this joint being of considerable in the following claimsis intended to comprehend any bending of the edge whereby the same isartially or entirely folded toward the body of the blank; and it mayalso be noted that the expression soldering is used in a broad sense asincluding any method of sealing the completed joint.

Referring now to the resultant device, it may be noted that there isprovided a seam possessing the high degree of strength characteristic ofthose of the interlockmgtype, and yet the portions over which the headis to fitare of lap joint conformation, thus presenting merely twothicknesses of material and adapting the body for eflicient connectionwith the edge ofthe head.

are attained and that the same possesses the favorable characteristicshereinbefore mentioned. v

As many changes could be made in the above method of c rrying on my art,and as the same could be arried on through the use of widely diflfere'nimplements, it is intended that all matter contalnedin the abovedescription or shown in the accompanying drawings shall be interpretedas illustrative and not in a limitin sense. It is also to be understoodthat the anguage used in the following claims is intended to cover allof the generic and specific features of the invention herein describedto which said claims relate and to which I am entitled over the priorart.

Having described my invention, what I claim as new and desire to secureby Letters Patent is: 4

1. The art which comprisescutting away the corner portions of a blank,flanging the edge comprehended between said portlons, flanging theopposite edge of the blank throughout a portion of its length,interlocking said flanged edges with the unflanged portion overlappingand resting upon the corresponding portion of the opposite edge, andsoldering the opposite edges in assembled relation throughoutsaidinterlocking and overlapping portions thereof.

2. The art which comprises cutting away the corner portions of a blank,flanglng the edge comprehended between said portions,

flanging the opposite edge of the blank throughout a portion of itslength, interlockmg said flanged edges with the unflanged portionoverlapping and resting upon the corresponding portion of, the oppositeedge,

compressing sa1d interlocked portions, and soldering the opposite edges1n assembled relation throughout the lnterlocking and overlappingportions thereof.

3. The art which comprises cutting away the corner portions of a blank,flanging the edge comprehended between said portions, formin spacedincisions in the opposite edge 0 said blank, flanging the portionsbetween saidincisions, interlocking said flanged edges with theunflanged portion of each of the same overlapping and resting upon thecorresponding portion of the other thereof, and soldering the oppositeedges in assembled relation throughout said inter locking andoverlapping portions thereof.

4. The art which comprises cutting away the corner portions of a blank,flanging the edge. comprehended between said ortions, formingsubstantially \l-shaped incisions in the opposite edge of said blank,flanging the portions between said incisions, interlocking said flangededges with the unflanged portion of each of the same overlapping and 1restin upon the corresponding portion of v It will thus be seen thatthere is provlded an art in which the objects of my inventlon the ot erthereof, and soldering the opposite edges in assembled relationthroughout said interlocking and overlapping portions thereof. I

The art which'comprises cutting away portions of one edge of a blank,flanging the entire remaining portion of said edge,'forming incisions inthe opposite edge spaced at a distance substantially equal to theflanged portion of said first edge, flanging the portion comprehendedbetween said incisions, interlocking said flanged portions, andsoldering the same in assembled relation.

8. The art which comprises cutting rectangular corner portions om oneedge of a blank, flanging the edge portion comprehended therebetween,forming substantially \l-shaped incisions in the opposite edge of saidblank, said incisions belng spaced at a distance substantially equal tothat of said flanged edge, fianging the edge between said incisions,interlocking said flanged portions with the unflanged portions of oneedge overlapping and resting upon the corresponding portions of theopposite edge, compressing said interlocking portions, and soldering theopposite edges in assembled relation throughout the interlocking andoverlapping portions thereof. 7

9. The art which comprises cutting away portions of one edge-of a blank,flanging the entire remaining portion of said edge, flang- 4 ing aportion of the opposite edge substanof the ual in length to the flangedportion rst edge, interlocking said flanged portions, and soldering thesame in assemtially bled relation.-

10. The art which comprises cutting away I a corner portion of one edgeof a blank, fianging another portion of said edge, forming an incisionin the opposite edge of the blank to define a tongue that will overlapsaid cut-out portion when the edges are interlocked, flanging a portionof said opposite ed e substantially e%ual in length to the flangeportion of the rst edge, interlocking said flanged portions, andsoldering the same in assembled relation.-
